How can I create if-then: the following describes what I am trying to implement

 if field A has a specific value require selection of field B otherwise no

(only) when  team = HW

then 

HW-Unit is required ( workflow validator)

Hi @eleanor kerman ,

your request is similar to this one.

That said, you should look for a workflow app capable of interpreting Jira expressions (see https://marketplace.atlassian.com/search?category=Workflow&product=jira) and an expression like the following with 12345 being your team and 67890 your HW-Unit custom field:

issue.customfield_12345 != "HW" || issue.customfield_67890 != null

Cheers
